Disclosed are processes for preparing a protected trifluorothreonine, or salt thereof or carboxylate derivative thereof, the process comprising: dihydroxylation of an alkene to yield a dihydroxyl compound; conversion of the dihydroxyl compound to a monohydroxyl compound; protection of the monohydroxyl compound to yield an azide compound; transformation of the azide compound to yield an amino compound; protection of the amino compound to yield a protected amine compound; and oxidation of the protected amine compound to yield the protected trifluorothreonine. Also disclosed are compounds having the structure:
or salt thereof or carboxylate derivative thereof, wherein P
2
is a hydroxyl protecting group, and wherein P
3
is an amine protecting group. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
